The Hubble Deep Field provides one of the deepest multiwavelength views of the distant Universe and has led to the detection of thousands of galaxies seen throughout cosmic time. An early map of the Hubble Deep Field at a wavelength of 850micrometres, which is sensitive to dust emission ...
Hubble’s deep field observations tell us that the number and shape of galaxies in the early universe were very different from what we see today. JWST will push the range of what we can see further back to the first galaxies, and be able to “witness” how they grew and evolved. ...

But no image has revolutionized the way we understand the universe as much as the Hubble Deep Field. Taken over the course of 10 days in 1995, the Hubble Deep Field captured roughly 3,000 distant galaxies varying in their stages of evolution, stunning the world. This video features some of...
Determining when most of these stars formed is one of the central issues of observational cosmology. Optical and ultraviolet observations of high-redshift galaxies (particularly those in the Hubble Deep Field) have been interpreted as indicating that the peak of star formation occurred between red...
A brief summary of some recent research on the Hubble Deep Field is presented. Particular attention is paid to the incidence of strong gravitational lensing and it is argued that the optical depth is nearly ten times smaller than average. Preliminary estimates of the incidence of galaxy-galaxy le...

The deep-sky mosaic, created from nearly 7,500 individual exposures, provides a wide portrait of the distant universe, containing 265,000 galaxies that stretch back through 13.3 billion years of time to just 500 million years after thebig bang. The faintest and farthest galaxies are just one ...
Fernandez-Soto, Lanzetta, & Yahil (1998) derive a photometric redshift of z(ph) = 5.28 (+0.34,-0.41; 2 sigma) for these galaxies; our integrated spectrograms show a large and abrupt discontinuity near 7710 (+- 5) Angstroms. This break is almost certainly due to the Lyman alpha forest...
A Submillimetre Survey of the Hubble Deep Field: Unveiling Dust-Enshrouded Star Formation in the Early UniverseAstrophysicsThe advent of sensitive sub-mm array cameras now allows a proper census of dust-enshrouded massive star-formation in very distant galaxies, previously hidden activity to which ...
